Safety. Xin Jia Xiang Ru Yin is recorded in the Wenbing Tiaobian of Wu Jutong, and its name says what it is: the old Xiang Ru preparation with something newly added. Where the Song formulary's powder held three ingredients — the acrid-warm herb, the bean and the magnolia bark — this one keeps the herb and the bark and replaces the bean with fresh lablab flower, then adds honeysuckle flower and forsythia fruit. It is a warm-acrid pair with three cool ones.
That combination is the interesting part, and it is also the part a reader is likely to read backwards. Someone who arrives at a category named for summer heat expects cooling. What the classical indication actually describes is a person with aversion to cold and fever and no sweating — the cold side — who at the same time is thirsty with a flushed face — the heat side. Wu Jutong wrote at length about exactly this kind of presentation, because it looks like a cold damage pattern and is not one, and because a physician who treated only the chills with warm-acrid herbs would drive the heat further in. The warm half is here to open the surface; the cool half is here to meet the heat that is already present. Neither half makes sense without the other, and the formula is a record of a tradition arguing with itself about which error is worse.
What it is not is a treatment for heat stroke. It is worth repeating here because the category name invites the mistake. Heat stroke is a core temperature above 40°C with disturbed brain function; it is treated by rapid cooling and emergency transport, on a timescale of minutes, and a person with hot skin and altered mental state in the heat belongs on that pathway, not in a pattern. The classical indication for this formula is a febrile illness at its beginning in a person who is still fully conscious.
Three of the five ingredients need a note. Jin yin hua is the flower of Lonicera japonica. It has a namesake that is a different plant: shan yin hua comes from other Lonicera species, has a different saponin profile, and has been associated with adverse reaction reports around injectable preparations. This library does not treat the two as interchangeable. Honeysuckle flower itself is credited with a low order of toxicity, but allergic reactions including contact dermatitis and urticaria have been reported, and it is one of the most common botanical ingredients in proprietary products, so it is worth asking what else is in the box. Forsythia fruit is generally well tolerated and can upset the stomach. Magnolia bark carries the sedative and muscle-relaxant signal from magnolol and honokiol, so an additive effect with sedative medication is at least plausible; wild magnolia is protected in China and commercial supply comes from cultivation. Fresh lablab flower is a flower rather than the bean, but it is the same species, and fresh plant material spoils and carries microbial and residue questions that dried material does not.
This page is not a recommendation. No quantity, no preparation, no regimen, no claim of benefit. Pregnancy, breastfeeding, children, older adults, impaired liver or kidney function, and any sedative, antipyretic, diuretic or anticoagulant medicine taken on medical advice each remove the room. If a preparation like this has been taken and there is persistent vomiting, localising abdominal pain, rash with swelling or breathing difficulty, tremor, or confusion, treat it as an emergency and bring the packaging.
新加香薷饮著录于吴鞠通《温病条辨》，方名已经说明了它是什么：在旧的香薷散之上「新加」。宋代方书的三物香薷散是辛温的香薷、扁豆与厚朴；这一首保留香薷与厚朴，把扁豆换成**鲜扁豆花**，再加金银花与连翘。辛温两味配辛凉三味。
这个组合才是值得看的地方，也正是读者最容易读反的地方。看到「祛暑」二字，人预期的是清凉。而古典主治描述的是一个**同时具备两侧**的人：恶寒发热、无汗（寒的一侧），同时口渴、面赤（热的一侧）。吴鞠通对这类表现论述极多，正因为它形似伤寒而实非伤寒 —— 只看到恶寒而专用辛温，会把热往里赶。方中温的一半负责开表，凉的一半负责迎接已经在里的热；少了哪一半都不成其为这首方。它是一份记录：一个传统在内部争论，哪一种错误更不可原谅。
它不是治热射病的方。这一点在本条仍需重述，因为类别名本身就在引人犯错。热射病是核心体温超过 40℃ 伴中枢功能异常，处理是快速降温与转运，时间以分钟计；皮肤灼热伴意识改变的人属于那条急救路径，而不是一个待辨的证。本方的古典主治是热病初起、神志仍清之人。
五味里有三味需要注脚。**金银花**是忍冬（Lonicera japonica）的花，它有一个同名而异物的对照：**山银花**来自忍冬属的另一些植物，成分谱不同，且曾与注射剂的不良反应报告相关；本库不认为二者可以互换。金银花本身一般认为毒性低，但接触性皮炎与荨麻疹一类过敏反应有报告，而且它是最常见的成药成分之一，所以值得问一句盒子里还有什么。**连翘**一般耐受良好，可引起胃肠不适。**厚朴**沿上条的注脚：和厚朴酚与厚朴酚的镇静与肌松信号，与镇静类药物叠加至少是可能的；野生厚朴在国内受保护，商品来自栽培。**鲜扁豆花**虽是花不是豆，却是同种植物的花，且鲜品会腐败，并有干品所没有的微生物与残留问题。
本页不是建议：不列用量、不列制法、不列服法，也不主张它对任何情况有益。妊娠、哺乳、儿童、老年、肝肾功能受损，以及正在使用镇静／解热／利尿／抗凝类处方药，任何一项都足以抹去空间。若已服用此类制剂并出现持续呕吐、逐渐固定的腹痛、伴肿胀或呼吸困难的皮疹、震颤或意识改变，属急症：立即就医，并把原包装带上。
